Release notes: This comment was posted by Codex Desktop using gpt-6.1-sol on behalf of David. What's Changed 🛡️ Security High — HTML conversion in web fetch : GHSA-4whf-38hw-pxxh (https://github.com/pydantic/pydantic-ai/security/advisories/GHSA-4whf-38hw-pxxh). When web fetch tool fetched attacker-controlled HTML containing many elements, conversion could delay unrelated work in the same process. Fixed in v2.59.0 and v1.107.9. Upgrade if the tool can fetch such pages. Full Changelog : https://github.com/pydantic/pydantic-ai/compare/v1.107.8...v1.107.9
